Аннотация:A diffusion-drift two-liquid two-temperature model of a gas-discharge plasma is used todescribe the electrodynamic structure of the Penning discharge in molecular hydrogen at a pressure ofthe order of 1 mTorr. The effect of the discharge chamber’s geometrsic parameters, variations in theEMF of the power supply of an external electrical circuit, and the axial magnetic field induction onthe discharge structure is studied by numerical simulation. The determining role of the flow of highenergyelectrons formed during the azimuthal motion of plasma flows around the axis of symmetry ofthe discharge chamber on the ionization of neutral gas is shown. The modes of the quasi-monotonicand oscillatory averaged motion of charged particle fluxes in the axial regions are found.
